The record-breaking wave of artificial intelligence investments has sparked fierce debate across global markets, with opinions divided over whether the sector is inflating into a bubble reminiscent of the early 2000s dot-com frenzy.
According to Bank of America Global Research, 54% of surveyed fund managers now believe AI stocks are in a bubble, compared to 38% who disagree. The discussion has gained urgency as companies pour hundreds of billions into AI infrastructure, data centers, and startups, pushing valuations to new extremes.
The Bank of England warned that a sharp market correction tied to fading AI optimism could ripple through the global financial system. “The risk of a sharp market correction has increased,” its Financial Policy Committee said in an October update.
Singapore’s GIC investment chief Bryan Yeo also described “a little bit of a hype bubble” in the venture space, saying startups labeled as AI firms are being valued “at huge multiples” of modest revenue.
Amazon founder Jeff Bezos offered a nuanced view, saying industrial bubbles often leave lasting benefits even if many investors lose money. “When the dust settles and you see who are the winners, society benefits from those inventions,” he said.
Others, such as Goldman Sachs economist Joseph Briggs and ABB CEO Morten Wierod, argue the AI investment surge remains justified given long-term potential — though both caution about bottlenecks in infrastructure and human resources.
By contrast, Michael Burry — famed for predicting the 2008 financial crisis — has bet against high-flying AI stocks like Nvidia and Palantir, warning that the boom mirrors past speculative manias.
IMF chief economist Pierre-Olivier Gourinchas agreed that a correction could come but emphasized it would likely be contained. “This is not financed by debt,” he said, meaning any fallout would primarily hurt equity investors.
OpenAI CEO Sam Altman echoed that sentiment, admitting that investors may be “overexcited” and predicting that “someone is going to lose a phenomenal amount of money.”
Yet, UBS strategists note that even among those who believe in an AI bubble, about 90% are still invested — a sign of the sector’s magnetic pull despite growing caution.
